I have a Roxim Z3EK bicycle headlight. This light is supposed to have a low and high beam function, but I can only get the low beam to work. So far, I have tried:

  • grounding the green wire
  • sending 12V+ to green
  • sending 12V- to green
  • bridging the green and black wires
  • bridging the green and white wires

I emailed the manufacturer asking for a wiring diagram, but no response.

I appreciate any guidance y'all might have. Thanks!

I suppose you don't have the original power source, if you did then measuring the output would be my starting point.

If it's LED then it'll probably be a single LED using PWM. In that case try figuring out where the switching circuit is.

If it's not LED, you should measure resistance between the wires, that would tell you which one is the common. .
